Multitarget Tracking

By itslemonade on Wed, 08/16/2017 - 12:00

Morning,

WE are developing an app that will need to track a big wall, so we decided to give MultiTarget a try, but it's not working. If I try to track one part of the image, as a ImageTarget, it works fine, but when I change it to Multitarget, nothing happens. My XML looks like this:

<QCARConfig xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="qcar_config.xsd">
  <Tracking>
    <ImageTarget name="post3" size="1.000000 1.414427" />
    <ImageTarget name="post1" size="1.000000 1.000000" />
    <MultiTarget name="Dancing">
      <Part name="post1" translation="0 0 0" rotation="AD: 1 0 0 0"/>
      <Part name="post3" translation="0 .5 .72" rotation="AD: 1 0 0 90"/>
    </MultiTarget>
  </Tracking>
</QCARConfig>

Can someone help with this?

Hello itslemonade,

Is the wall you are tracking entirely flat, or does it have a corner? If it is flat, you'll want to remove the rotation value of the Part called "post3" in your XML. That rotation value is making Vuforia expect rotation in the second image.
